The US government's own Combined DNA Index System (CODIS) database is composed of forensic evidence assessable to local, state, and federal law enforcement officials. This database consists of genetic profiles of approximately 18 million different people, however these are limited to DNA samples from convicted felons and arrestees. [26]
DNA information from crimes is collected and deposited into the CODIS database, which is maintained by the FBI. CODIS enables law enforcement officials to test DNA samples from crimes for matches within the database, providing a means of finding specific biological profiles associated with collected DNA evidence.

The Combined DNA Index System (CODIS) is the United States national DNA database created and maintained by the Federal Bureau of Investigation.CODIS consists of three levels of information; Local DNA Index Systems (LDIS) where DNA profiles originate, State DNA Index Systems (SDIS) which allows for laboratories within states to share information, and the National DNA Index System (NDIS) which ...
The researchers used data from 17 actual cases to test their model. In each case, the target’s DNA—that of the suspect or the victim—produced anywhere from 200 to 5,000 matches.
By Carolyn Crist (Reuters Health) - With recent revelations that U.S. law enforcement can - and already has - dipped into consumer genealogy DNA databases to help solve crimes, experts say more ...
In Smith's case, scientists used genome sequencing to build a DNA profile for the murder suspect, according to Othram Inc., a labratory that specializes in forensic genetic genealogy to assist law ...
Developed in 1991, [10] DQ alpha testing was the first forensic DNA technique that utilized the polymerase chain reaction. [11] This technique allowed for the use of far fewer cells than RFLP analysis making it more useful for crime scenes that did not have the large amounts of DNA material that was previously required.
